The motorola phones are neat, especially razr's, but practically disposable with their dismal update support lasting in some cases only a year or a major version I'd read. Selling me a $1500usd flip phone that is practically disposable oob for updates is a non-starter.
Now put GrapheneOS on it with better support than the vendor can provide, now that's highly appealing. I wanted to get a used pixel 9 pro xl to update my old pro 6 and run graphene on, but pixel 9xl have defective screens on whole, so maybe not, and with Graphene divesting from pixel hardware now, maybe this is the way.
Motorola Signature (2026) has 7 years of support. It's a subset of Motorola's future devices in 2027 and later which are going to support GrapheneOS since the current ones in 2026 didn't quite meet all of the requirements yet. The intent has never been to support their existing devices but rather for future devices to provide everything needed and official GrapheneOS support. There's a lot of work to do. Meeting all of our requirements on low-end devices is currently unrealistic but can be a goal further down the road.
Adding graphene doesn't extend the support lifespan, it still depends on manufacturers for low-level security patches.

grapheneos has a hard requirement for the vendor to provide software support for 6+ years (iirc), so i expect the updates will be better even for stock users
however this might be only for their new Motorola Signature line of flagships...
